Mini-Quencher Spark Arrestor, Spark Trap

Recognized as the world leader in spark arresting technology

Ideal for Vacuum Systems (2″ to 4″ tubing); the Mini-Quencher

An extension of our highly acclaimed Quencher spark arrestor product line. A static device, with no moving parts.The spark trap “cell” consists of overlapping turbulation vanes in a round housing, thereby creating maximum agitation and turbulence of the air stream. Turbulence strips the oxygen (fuel) away from the spark/ember, thereby extinguishing it. The hot air envelop surrounding the spark/ember, being removed by high speed agitation immediately cools the spark/ember to the low temperature of the air stream.

Mini-QUENCHER spark arrestor (or spark trap) is designed and built specifically for spark arresting and cooling. It is not a renamed air blender or mixer.

How the Mini-Quencher Spark Arrestor Works

Laminar flow in ducts; (1) creates a hot air envelop (800°F) around the spark/ember (1400°F) and feeds oxygen to the spark, (2) the spark is buoyed up and floats along in the gas stream for 100 feet or more.

The Mini-QUENCHER spark arrestor (spark trap) creates extreme turbulence and breaks apart the envelop, strips the oxygen (fuel) away from the burning spark, extinguishing and cooling it. The temperature of the spark, leaving the Mini-QUENCHER, is now too low to cause an ignition and fire. The cooled sparks are safely carried along the gas stream to the dust collector.

CAUTION: Air mixing or blender devices, being marketed as spark suppressors and spark coolers, do not create enough turbulence and have large gaps in the cells, permitting sparks to slip through and set fire to the dust collector.
